R Documentation

Generic spde2 model creation.

Description

Creates and inla.spde2 object describing the internal structure of an 'spde2' model.

Usage

inla.spde2.generic(
  M0,
  M1,
  M2,
  B0,
  B1,
  B2,
  theta.mu,
  theta.Q,
  transform = c("logit", "log", "identity"),
  theta.initial = theta.mu,
  fixed = rep(FALSE, length(theta.mu)),
  theta.fixed = theta.initial[fixed],
  BLC = cbind(0, diag(nrow = length(theta.mu))),
  ...
)

Arguments

`M0`	The symmetric `M0` matrix.
`M1`	The square `M1` matrix.
`M2`	The symmetric `M2` matrix.
`B0`	Basis definition matrix for phi0.
`B1`	Basis definition matrix for phi1.
`B2`	Basis definition matrix for phi2.
`theta.mu`	Prior expectation for the theta vector
`theta.Q`	Prior precision for the theta vector
`transform`	Transformation link for phi2. Valid settings are `"logit"`, `"log"`, and `"identity"`
`theta.initial`	Initial value for the theta vector. Default `theta.mu`
`fixed`	Logical vector. For every `TRUE` value, treat the corresponding `theta` value as known.
`theta.fixed`	Vector holding the values of fixed `theta` values. Default `=theta.initial[fixed]`
`BLC`	Basis definition matrix for linear combinations of `theta`.
`...`	Additional parameters, currently unused.
`spde`	An `inla.sdpe2` object.
`theta`	parameter values to be mapped.

Value

For inla.spde2.generic, an inla.spde2() object.

For inla.spde2.theta2phi0/1/2, a vector of phi values.
